ABSTRACT:
To produce a sintered metal type brake friction element which beds-in quickly and which has a "feel" similar to a resin-based element, powdered metallic friction material is subjected to a resistance sintering or furnace sintering operation, so as to produce a sintered substrate and an unsintered or partly sintered surface layer which has less wear resistance than the substrate but friction properties which are not substantially less than the substrate. The surface layer may be formed of the same or different material as the substrate layer depending upon the sintering technique chosen.
